A force actuator comprising an output member (1) movable from a first position to a second output-force-exerting position; first operating means (2) connected by a first transmission path (3) to the output member (1), and second operating means (20) connected by a second transmission path (23) to the output member (1); the ratio of the transmission paths, (3,23), the inertia of the respective transmission paths (3,23) and the operating means (2,20) connected thereto and the accelerating force capable of being generated by the respective operating means (2,20) and transmitted via the transmission path (2,23) connected thereby to the output member (1) all collectively being such that, with the output member (1) in its first position, simultaneous initiation of the operating means (2,20) causes the first operating means (2) to constitute the prime means by which the output member (1) is moved to its second position and, when in that second position, the second operating means (20) constitutes the prime means by which the output member (1) is caused to exert the output force. |
